2. Description of the Related Art When a tile floor surface such as a balcony or an entrance is to be constructed, the wet method requires a professional craftsman and cannot be constructed by anyone. Therefore, there is provided a composite flooring material capable of easily constructing a tile floor surface by a dry method. As a stationary floor type composite floor material of this type, a material disclosed in Japanese Utility Model Laid-Open No. 3-68254 is conventionally known. This composite flooring material is formed by joining tiles to the upper surface of each tile laying portion of a resin mat having a plurality of tile laying portions arranged in a grid pattern. FIG. 4 is a plan view of the conventional composite floor material 1 described in the above publication, FIG. 5 is a plan view of a resin mat 2 used in the composite floor material 1, and FIG. FIG. 3 is an exploded perspective view showing a main part of FIG.

The resin mat 2 has a square substrate portion 3 formed in a grid pattern, and is formed on the upper surface of the substrate portion 3 in a matrix of 3 vertically and horizontally.
A total of nine tile laying portions 4 are sectioned and formed as recesses, and square tiles 5 are placed on the upper surface of each tile laying portion 4. Further, the partition walls 6 that define each tile laying portion 4 are provided with projecting tile holding pieces 7 at each of the four corners.
The tile 5 is fixed to the resin mat 2 by pressing the four corners of the tile 5 housed in the tile laying portion 4. Further, the hook portion 8 is provided on two adjacent sides of the resin mat 2, and the engaging portion 9 with which the hook portion 8 engages is provided on the remaining two sides. The hook portion 8 and the engaging portion 9 fulfill the function of connecting the resin mats 2 of the adjacent composite floor materials 1 when a plurality of composite floor materials 1 are laid. In addition, the back surface (lower surface) of the resin mat 2 is provided with a support leg portion 3a including a protrusion or a protrusion. The support legs 3a are for securing a space for circulating rainwater or the like between the composite floor material 1 and the floor base surface on which the composite floor material 1 is placed. In the above composite floor material 1, the tile 5 is fixed to the resin mat 2 by the tile holding piece 7 provided on the partition wall 6, but as another example, a collar piece having diagonally downward elasticity on the partition wall. Which supports the side portion of the tile by the flange piece (Japanese Utility Model Publication No. 4-7205, etc.), and which fixes the tiles to the resin mat with an adhesive (Japanese Utility Model Publication No. 6-14344, Japanese Utility Model Publication No. 3-143). No. 3,2561, etc.), and when the tile is a wooden brick, those that fix the brick with screws from below (Japanese Patent Laid-Open No. 4-85401, etc.) are known.

[0004]

By the way, in the conventional composite flooring, since the tile is directly placed on the tile laying portion and fixed by the holding piece, the collar piece, the adhesive, the screw, etc. The position could not be adjusted in the height direction.
Therefore, if the floor surface has irregularities or slopes (uneven),
There was a problem that the effect was directly reflected on the surface of the tile. The present invention has been made in view of the above circumstances, and provides a composite floor material capable of preventing the influence of the unevenness or inclination of the floor base surface from appearing on the tread surface such as tiles. Is intended.

[0005]

In order to solve the above-mentioned problems, the invention according to claim 1 is a composite floor comprising a resin mat having a substrate portion and a tread joined to the upper surface of the substrate portion of the resin mat. In the material, on the upper surface of the substrate portion, a large number of pillars having an elastic portion at the upper end are erected upright, the tread is placed on these many pillars, and bolts are attached to the pillars from the lower surface side of the substrate portion. It is characterized in that the tip end of the bolt is screwed into a nut embedded in the lower surface of the tread plate to join the tread plate and the base plate section through the support column.

[0006]

According to the first aspect of the invention, the tread plate is placed on a large number of columns having elastic portions at the upper ends thereof, and the tread plates are fixed by bolts from below, so that the upward reaction force of the elastic portions of the column is resisted. Thus, the vertical position of the tread can be adjusted by adjusting the screwing amount of the bolt. Therefore, even if the resin mat is placed on the uneven or inclined floor base surface, the influence can be absorbed.
